ANTISKI D SHOE ATTACHMENT Filed Q01'..- 28, 1938 a so 300 INVENTOR (Aer/es f: Muller ATTORN EY Patented Aug. 22, 1939 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to new and useful improvements in a non-skid shoe attachment.

More specifically, the invention proposes the construction of a non-skid shoe attachment char- .5 acterized by the provision of a fiat body for engagement upon a shoe and having a plurality of blades attached obliquely across the bottom thereof in a particular manner and provided with serrated bottom edges for gripping ice or snow to assist one in walking.

Still further the invention proposes the provision of a plurality of bars mounted on said flat body and extended substantially at right angles to said blades for assisting in rigidly holding said blades in position.

Another object of this invention is the provision of fibre members mounted on the sides of said blades along said serrated bottom edges with the bottom edges of said fibre members being flush with the bottom edges of said blades in a particular manner to protect ones hands or fingers from coming in direct contact therewith.

Still further the invention proposes the provision of a flat body for attachment on the sole of a shoe and having a plurality of spring pressed plungers mounted therein and having their bottoms serrated and extended from said body to engage the snow or ice.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a mate rial part of this disclosure:

Fig. 11 is a sectional view on the line ll-l I of :5 Fig. 10.

Fig. 12 is a view similar to Fig. 1 but illustrating a still further modification of the invention.

The non-skid shoe attachment, according to this invention, comprises a fiat body ID for ex- =10 tending across the sole and heel of a shoe II. The fiat body IE3 is constructed of heavy cloth material or other similar material and is pro vided with a means for supporting it in an extended position across the sole and heel. This 16 means comprises a toe strap l2 consisting of a toe strap section l2 attached to one side of the body it and engageable across the toe of the shoe and upon a second toe strap section It! attached to the other side of the body l0.

Complementary snap fasteners l3 are provided upon adjacent faces of the strap sections M and it" for holding the front end of the body in position on the sole of the shoe I I. A heel engaging portion i4 is provided on the back end of the 25 body it and is engageable upon the heel of the shoe H. A strap I 5 is provided for engaging around the shoe in the vicinity of the ankle and comprises a strap section W attached to one side of the heel portion M and engageable upon a .30 strap section ifi mounted on the other side of the heel portion I 4. Complementary snap fastener elements it are provided on the strap sections lfi and 15 for supporting the back end of the flat body upon the heel of the shoe H.

A plurality of blades I? are attached obliquely upon the bottom of the body l9 and have serrated bottom edges H for engaging snow or ice on the streets for assisting one in walking. The blades are formed at their upper ends with oppositely extending lugs 81* having openings [8 through which rivets 9 are adapted to be passed for holding the blades I! in position upon the bottom face of the flat body It.

A plurality of bars 20 are mounted on the flat 45 body Hi substantially at right angles to the blades I! for assisting in maintaining the blades rigidly in position. The bars 2!] are also formed with lugs Zit directed in opposite directions and formed with openings 2! through which rivets 22 may be .50 passed for attaching the bars to the bottom of the flat body MI. The bottom edge of the bars 20 are formed with inwardly extending cutouts 20* which are adapted to engage complementary cutouts li formed in the top edges of the blades 55 I! where the bars and blades cross for permitting them to be formed of continuous strips and still pass each other. An inspection of Fig. 4 will reveal that the sides of the cutouts 20 formed in the bars 2!! engage upon either side of the blades H for assisting in maintaining them in their vertical position with relation to the fiat body ID.

A plurality of fibre members 23 are mounted on the sides of the blades ll along the serrations Il The bottom edges of the fibre members 23 are flush with the bottom edges of the blades H for partially covering the same to prevent ones hands and fingers from contacting therewith while the shoe attachment is being engaged upon ones shoe. These fibre members 23 are in the form of ropes or similar members and are maintained in position on the sides of the blades by means of extending lugs 24 stamped from the vertical portions of the blades and which are engaged around the fibre members 23. The ends 2t of the lugs 24 are engaged into the side of the fibre members for rigidly maintaining them in position upon the blades 11.

The operation of this device is as follows:

The sole and heel of ones shoe is rested on the top face of the fiat body I!) and the straps l2 and 15 are engaged around the shoe for maintaining the flat body in a position extended across the sole and heel of ones shoe. The fibre members 23, while the attachment is being engaged upon ones shoe, will remain flush with the bottom edge of the blades H to prevent the serrations Il from cutting ones hands and fingers. However, when the weight of the body is rested upon the fiat body It] it will cause the serrations W to be slightly extended beyond the bottom edge of the fibre members 23 by slightly compressing the same against the lugs 24 to permit the serrations IT to engage the snow and ice to assist one in walking thereon.

According to the modification of the invention shown in Fig. 9 the construction of the non-skid shoe attachment is similar to that previously described, distinguishing therefrom merely by the inclusion of a strand of cord or wire 25: which is wound upon each of the fibre members 23 for providing additional elements for assisting one in walking upon ice or snow. In this form of the invention when the weight of the body is rested upon the flat body N1 the fibre members will be compressed and the cord or wire 25 will also assist the serrations I! in gripping the ice or snow. In other respects this form of the invention is similar to the previous form.

According to the modification of the invention shown in Figs. 10 and 11 the non-skid shoe attachment includes a fiat body 26 having a plurality of inwardly extending openings 25 The fiat body 26 is adapted to be extended across the sole of ones shoe and be maintained in position by means of a toe strap 21 which has its ends attached to opposite sides of the fiat body 25 by means of nails or rivets 28.

A plurality of plungers 29 are slidably engaged into the openings 28 and extend inwards from the bottom of the body 28. Each of the plurlgers 29 is formed with a reduced extension 29 and a plate 38 is extended across the bottom of the body 26 and is maintained in position by means of screws M. The plate 36 is formed with a plurality of openings 39 through which the reduced ends 29 of the plungers 29 extend. The bottom face of the reduced portions 29 are formed with a plurality of serrations 253 which are adapted to engage the snow or ice for assisting one in walking thereon. Springs 32 operate between the top faces of the plungers. 29 and the upper end of the openings 26 for urging the plungers 29 into their extended positions.

In Fig. 12, the fiat body It! is extended across the sole of a ladys shoe H with high heel II and held thereon by a strap I2 or any other suitable manner. This fiat body includes the serrated blades I1 and the fibre members 23. Another fiat body 26 is held by strap 12' or the like and includes a spring pressed plunger 29 with serrations 29 as previously described. This form of the invention is especially arranged for high heeled shoes.

It is to be understood that this non-skid device may be secured on all types and sizes of shoes, including rubber shoes and the serrated members are preferably made of aluminum or other noncorrosive material while the fibre members may be of Jude rope, canvas or like materials.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims. 7
